Question

The Humboldt Current, a river of cold water running deep beneath the Pacific Ocean, sweeps eastward toward the South American coast until it hits the coastline where it is forced upward near the surface. Deep sediments come up along with the cold water. Predict what you would find along that coast

Answer 1

Answer:

Biological diversity.

Explanation:

• The Humboldt is also called as the Peru current and is cold, low in salinity current, flows along the western coasts of South America.

• This current extends from the southern Chile to northern Peru here the cold water upwelling intersects the warm tropical waters of the equatorial current.

• Here the temperatures range from 15 to 25° C. This brings the nutrients to the surface that are important for the growth of the phytoplankton and ultimately increases the biological productivity.

• This current has a highly productive ecosystem with large species of fish like the jack mackerel, and other seabirds etc.

• Sardines fish is typically found in offshore areas along the coasts as this zone has seen huge upwelling large scale biological productivity is found along the shores.
